To'allfwhom'it may concern: l e

Be it known that-I, FRANK J AGER, a citizen of the United States, residing at Chi-- cago, iii the county-'of Cook and State of Illinois,` have inventedcertain new and useof which the following is a specification, ref- Y yerence .being made to the accompanying i.drawings.

lf "tion` Vand more particularly to a railway i freighticar roof framework.

One of the objects of my invention is the provision pf. an improved framework for car 'roofs wherebythe car body is `more effectively braced and to provide a light and strongly braced car roof frame structure de- 'retain metallic plates composing a car roof; another object istosimplify, lighten and v. cheapen car 'roof construction by the proj lat .signed to .resist diagonal stress and particularly adapted and conformed to support and vision of an improved carline designed to 'obviate the use of purlins with carlines 1n such connection; a further object is the provision A,of-a carline adapted to brace the car :'.fj body and car roof against strainsland adaptf i .3fed tof-'adequately support the roof; and to las, tionI- attain by means of a construction illusthisjendffbroadly stated, my4 invention is to providel a welll braced and durable ca rroof whichis simple, inexpensive and positively weather-tight.

` These and -such other` objects as may hereinafter. appear or are incident to my inventrfated in preferred form in the accompanyy ing drawings, wherein "is a plan view ofa pprtion of a bodying my invention, showing the roofingplates and running board-broken faway to show the arrangement .and con- -'ff'orniation of the carlines.v

' a portion of the car siding and plates--as shown in unbroken portion of Figure 1.

Figure 2 is a transverse section through the car roof as shown in Figure l.

Figure 3 is a perspective of one of the K shaped carlines.

Figures -l and 5 are sections 'in the lines IV--IV and V-.V of Figure l respectively. lFigure 6 is a' detail drawing showing .one of the ridge beams.

Figure `I is a longitudinal section through In carrying out my invention it will be seen that I show a series of carlines applied My invention relates to new and useful improvements-in general to roof constructo a car body, each carline substantially of kK shape and'fastened in -series to thecar` bodv and to each other in such a manner as Patentea Jaa'. 20, 1.9-1.4; .-legl,

nionly usedwithcarlines in car roof construction. This` in itself is aneconomy and also aiords a light structure without in any way sacrificing the necessary strength desired in this connection. The roof proper comprises a series of metallic plates secured to the non-divergent member of the carlines and the plates are arranged toliave sufficient play so as to'yield to any diagonal strain-to the car body and roof andisadapted to take care of expansion and contraction incidental to'service conditions. It will also be seen'that the carlines are braced longitudinally in the series b rangement of ridge beams t ere between affording an efficient and inexpensive construction. v

Thilo I have shown my invention-.applied to a freight car roof, it is obvious that my improvements are applicable t'o other roofs andthe like in analogous structuresand I do not therefore wish to be-understood as limiting myself inthis respect to the precise embodiment shown.

By a reference to the drawingsllustrating my preferred'enibodiment it will be seen that the roof frame consists primarily of a set of ridge T bars 7 and a set ofs'ubstantially K shaped carlines 8. One ofthe complete carlines 8 is clearly disclosedL in Figure 3 and consists of two angle bars 9 and l0 of ordinary commercial shape which together constitute the complete carline 8.

the novel ar- Each angle bar has a horizontal top iange 1l and a vertical Side Harige 12, each,ca'rv line being in line longitudinally" one with the other throughout the length of the series extending between the sidings 13, and is further provided with a fiat rintermediate central portion 14 substantially the' widthof the T iron 7. n d y *The carline member 9 is substantially straight= that is non-divergent, the other member 10 has part ofits top Harige 11 folded over on its verticalange inwardlv tolos ward its component member 9 at the flat porl tion 1l. From this horizontalportilio'n 1st their ends. v member 10 has its ends divergent from the member 9, this inclination lor divergence beginning at the flat portion 1l and continu-v ing to its extremities preferably at the angle shown. Each of the members 9 and l10 has its end split between the two flanges 11 and 12 and in this way providing what I shall term lugs, the top flange in the members 9 and 10 having lugs 15 and 16 respectively,

slightly turned up to a horizontal position..

The vertical flange at the ends of the inember.9 has its lu" 17 turned transversely under its top flange and outwardly from its component member, and the ver-tical flange at. the ends of the member 10 hasits lug 18 turned transversely outwardly but in adirection away from its'top flange.

The carline 8 as shown in Figure 3 is perforated at 19 for the reception of suitable clamping elements such as rivets or bolts to form the complete carline. y

The car sidings are each provided with a side plate 20, tothe upper face of which the Y lugs 15 and 16 of the carline are secured by bolts 15a and 16a passing through suitable perforations 15b and 16b in each lug respectively. The transverse lug 17 of the member 9 is provided with holes 9b, the lug bear ing againstv the vertical side of the said plate 20. and as each of the carlines are adapted to be fastened together in series at their ends, the lug 1S also provided with holes 18b lies in a slightly different vertical plane to that of the lug 17 so that when the carlines are assembled longitudinallyy the car the lug 18 of one carline is spaced away from-the plate 20 sufliciently toA bear against the .face of the lug 17 in the adjacent carline with the holes 9" and 18b registering to receive bolts 9. In this way the carlines are fastened to each other and to the side plate 20 and siding 18.

The numeral 7 as already stated indicates the longitudinal T bar member located intermediate each carline 8,-.having its Vertical 11 of that member.

flange 7a. cut away at its extremities and the horizontal flange 7b turned downwardly to form flanges 21 as will be seen by a reference to Figure 6. When the T bar member 7 is used in connection with the carline 8 the flanges 21are perforated at 19a to register with the openings 19. In fastening the longitudinal members 7 to the transverse member 8, one of the flanges 21 of one T bar is centrally placed against. the vertical flange 12 of the member 10 at the flat portion 14 and the flange 21 of the next T bar 7 fits against the vertical flange 12 of the member 9, the T bar being bent slightly as shown at 22 to accommodate the top flange When assembled and fastened by the bolts 23 passing through the openings 19 and 19a the flattened portions 14 v and the top flange 7b of the member 7 are both members inclme downwardly toward I It wlll be seen also that the t all in the same plane and present an even hor1zontal surface, any unattached flange 21 being secured to the end plates (not shown).

The car roof proper consists of a series of metallic panels 2 4.- extending from ridge to eaves of the car. the inner upwardlyv flanged ends resting on the ridge bar being protected and covered by a cover plate 30. Une transverse'edge of each panel 2l is flanged upattendant plate 28 is positioned as shown in l Figure 5, with the outer face of the trough 27 against the vertical flange 12 of one of l the angle bars 9. The vertical margin 25 of the succeeding panel is placed within the rebent margin and is then fastened by the rivet 29 also passing through the free. edge of the plate 28 and the top flange 11 of the angle bar 9.

A cross sheath 31 is positioned over the ends of the cover plates 30 where they meet with the open upper ends oft-he rebent margins, and in this manner efl'ectually preventing the entrance of water at that point. The numeral 82 indicates a saddle block to whichvv is fastened the 'running board 33, which saddle block is shaped to fitover the cross .sheath and all the roofing members given additional fastening means in the bolt 34C which passes from the saddle vblock through the cross sheath to the T bar.

Referring again to Figure 5 it will be noticed that I show a longitudinal Vlip 25 on the flange 25 within the rebent margin 26,

and this has been provided to positively in-l sure water dripping directly from the lipinto the conduit beneath, instead of seeping down the vertical flange and cont-,hitting along the under side of the panel 24 into the car.

The entire construction is simple and effiroofing members and for the transverse brac,`

ingl of the car siding and plates, and yet' retaining the advantage of lightness in construction. Y

Having thus described my inventionzf'and illustrated its use what fclaim as:netvand` desire to obtainby Letters Patent is the fol` lowing 1.
